## Boundary

Objective receipts support or reject candidate change claims; musical taste still requires listening review.

## Listening Prompts

- Does the supported candidate match the requested musical intent?
- Is the changed part better balanced in the proof window?
- Did the proof window contain the musical material being judged?
- Would another section or speaker profile change the listening decision?

## Caveats

- This packet does not prove subjective mix quality.
- A supported candidate proves objective receipts and guardrails only.
- Ranking orders review; it is not a taste score.
- Section-energy and loudness-style metrics are review aids, not proof that a candidate sounds better.
- Keep or apply the candidate only after listening review.


## Active Lane Receipts

These receipts show whether declared required lanes stayed measurable in each proof window. They support deterministic guardrails only; they do not prove subjective mix quality.
